Hint: use this sphere figure and values. 

Q1. At any time t a particle of mass m move along i) ii) iii) 3 vii) viii) ix) x) xi) xii) SPHERE x + y +2=1 2=1-1 p=1 An appropriate figure Are there any constraints in the system? If yes mention it Degree of freedom Position vector Velocity. Acceleration Kinetic energy Potential energy Generalized coordinates Lagrangian E. Lagrange's equations of motion Conservation of total energy of the system.
